WEATHER-STRIP.

` To all wiz/om it may concern.'

Be it known that I,- GUsTAv LANGEFELD, ay citizen of the United city of Cincinnati, inthe county of Hamilton and State of Ohio, have invented certain new and useful Improvements in Weather- Strips, of which the following is a specification.

`My invention relates to that class of weather strips used more particularly in connection with hinged windows.

It consists essentially n providing a weather strip composed of astrip of metal combined with an auxiliary metal strip coiled together at the outside or sill side ofthe window frame and at the inner side of the window frame doubled or folded, the inner side being combined with means for raising or lowering the strip to impinge against the lower face of the sash frame or relieve said strip from impingement.

My weather strip is simple in construction, cheap of manufacture and eiiicient in use. Its various features and advantages will readily become apparent from the following specification.

part of this specification, Figure -1 is a perspective view of a window sash' and jamb, partly broken away to illustrate construction, with my weather strip in position. Fig. 2 is a sectional view taken at line X, X, of Fig. 1, the weather strip shown away from the lower side of the sash frame and not in impingement therewith. Fig. 3 is a similar view to that shown in Fig. 2, except -that the weather strip is shown ment with the lower side of the sash frame. Fig. 4 is an enlarged view of the weather strip and means for raising and lowering it the relation between said parts. Fig. 5 is a View of the means for raising and lowering the weather strip, partly broken away to illustrate construction.

The jamb is marked 1, the window sash 2, the window sill 3. The sash 2 is usually hinged at 4.

The weather strip consists of a metal strip 5 at its outer side coiled or curved around on rod or bar 6 and at its inner side doubled or folded, first extending upward and then bent (imvnward, the downward bend extending down beyond the strip 5. The upward bend States, residing at the the sills of swinging or in impingef or fold 8, a slight space is left between the folds 7 and 8, marked 9. An outer or auxiliary .strip 10, curled .or coiled; around the wire or rod 6, similarly to strip 5, extends out into the window sill 3 and has its outer edge bent down to form an elongated tang or cleatv 12, which is forced into the sill 3 to hold rigidly and tightly. At each end where the weather strip reaches the jamb, said j amb 1 is cut away or recessed as shown at 14 and the strip 5 is bent up as shown at 15, so that the strip 5 with its fold 7 at the inside and its upturned ends 15, may be said to form a pan. Themeans for raising and lowering the weather strip (or pan) 5 is connected `to said fold 8, andfconsists of a box 16 screwed to a sill or said windows are usually provided.v This box holds a rack 17 which moves up and down in the box, (see particularly Fig. 5). Inside the box 16, I place a pinion or small gear wheel 18 connected rigidly to a lever v19, the teeth on the pinion 18 meshing with the teeth on rack 17 when the lever 19 is moved forward or backward. The rack 17 carries a jaw 20 into which jaw passes the downward fold or bend 8 of the strip or pan 5, being securely connected to said strip 5, so that when the lever 19 is moved forward and backward the rack 17 which carries said jaw 2O will carry the pan 5 up and down with it as the pinion 18 meshes with said rack. One of these boxes and connections may be placed at each end of the weather strip as shown.

It will be readily seenthat the sash when swung in will slightly 'impinge against the coiled head 21 formed by the curved, coiled or curled ends of the st ips 5 and 10, rigidity and strength being given to said coiled head 21 by the bar 6; this in itself making a tight yjoint at the outside of the window. l/Vhen the lever 19 of the raising and lowering means is operated' to raise the strip or pan 5, the said strip or pan moves up and impinges against the lower face of the sash as shown in Fig. 3, the folds 7 and 8 rising above the lower edge of the sash and the ends 15 of the pan or strip I5 passing up into the recesses 14, thus forming a water tight and d ust. proof joint and also preventing air from entering through the window at the point where the weather strip is present, either Aalong the lower-edge of the window at the sill, or at the edges at the jamb, the water, rain or the like -always being turned outward to the sill, thus forming a the Window and tseomers. f en the weather strip is in this position the Window cannot be opened; If it is desired fto open the windowithe lever 19 is turned in an opposite directionand the strip Willbelowersd to a position shown in Fig. 2, when the sash can pass over the strip to an open position.

The strip may be formed of any other `shfifye l'or con-tour and from 'any material and be connected to 4the window *frame or csiii in any desired manner. l

The mea-ns for mising and ower'ing the strip may be off any other sonst-motion than that herein sindical-1y shown and described.
